SPECIFICATI N forming part of Letters Patent No. 625,548, dated May 23,1899.

Original application filed February 12, 1898, Serial No. 674,061.Divided and this application filed December 23,1898. erial No. 700,120.(No model.)

To to whom, it may concern:

Be it known that I, JEAN BAPTIsTE FONDU, a subject of the King ofBelgium, residing in Brussels, in the Kingdom of Belgium, have inventedcertain new and useful Improvements in the Manufacture of GlassTumblers, &c.; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.

The invention herein referred to constitutes a division of thesubject-matter of an application for Letters Patent filed by me in theUnited States Patent Oflice February 12,1898, Serial No. 674,061.

The invention relates ,to the manufacture of glass tumblers, and it hasreference particularly to a machine for forming faces and polishing thefaces thus formed upon the blown tumblers.

The invention consists in the improved machine for forming faces andpolishing the faces thus formed upon the blown tumblers and in thecombination and arrangement of the various parts,substantially as willbe hereinafter described and finally embodied in the clauses of theclaim.

The invention is fully illustrated in the accompanyin g drawings,whereinlike numerals of reference indicate corresponding parts in both figures,and in which- Figure 1 is a top plan view of the machine constitutingthe subject of this invention; and Fig. 2 is a vertical sectional Viewtaken on the line am of Fig. 1, certain parts of the machine beingremoved and others broken away.

In said drawings, 1 indicates a substantially circular base, upon whichis secured by bolts or other suitable means a top plate 2, and 3designates a support or frame of circular shape, but of considerablyless diameter than the base 1, said support or frame being centrallysecured upon the top plate 2. Projecting upwardly through said frame orsupport 3 and penetrating the top plate is asleeve 4, which has keyed toits lower end a notched and scalloped disk 5, Whoseupwardly-proabove theupper edge of the frame or support 3. The sleeve 4, as well as the disk8 and the notched and scalloped disk 5, is penetrated by a shaft 10, towhich is secured at the upper end thereof a substantially circular plate11, spaced from the disk 8 by an integral collar 12 and carrying uponits upper face a series ofcams 13 and tappets 14. To the lower end ofsaid shaft is secured a gear 15, which is arranged just beneath thenotched an scalloped disk 5.

It should be remarked that the sleeve 4 and the disk and the notched andscalloped disk which it carries and the shaft 10 and the circular plate11 and the gear 15 which it carries are revolu ble within theirrespective bearings.

16 designates a horizontal shaft having bearings in brackets 17 and 18,suitably disposed and secured to the base and top plate, respectively.19 designates a worm upon the inner end of said shaft, and 20 designatesdriving-pulleys for said shaft. The worm 19 is in engagement with theworm-wheel 21, which is mounted with a single finger-cam 22 and a pinion23 upon a stub-shaft 24, that is suspended from the top plate. Thepinion 23 is in engagement with the gear 15, and the cam 22intermittently engages the notched and scalloped disk 5.

25 designates vertical supports of the tum blerholders, said supportsbeing mounted upon the disk 8 at uniform intervals and being preferablyeight in number. Pivotally connected at its inner ends to each supportis a yoke 26, which is normally held in a substantially horizontalposition by means of a pair of springs 27 of approximately spiral shape,said springs being coiled about and secured to the bearing-pin 28 of theyoke and having their respective free ends extending to and over otherpins 29 projecting from the yoke. The yoke is penetrated by a spindle30, which is journaled therein and which carries elastic rings 31, oneof which is situated at or near the end of said spindle. Upon thesuccessively subjected to them.

cushioned mandrel which the spindle thus provided with the elastic ringsconstitutes is adapted to be received a tumbler 32, said tumbler beingheld in proper position with respect to the yoke by means of aspring-con trolled plunger 33, having a cushion at its inner end adaptedto bear against the bottom of the tumbler.

The spindle 30 carries rigidly secured thereto near its inner end atappet-wheel 34, so situated relatively to the tappets on the circularplate 11 as to have its teeth successively engaged by said tappets, soas to effect intermittent rotary movements of the spindle 30, andconsequently the tumbler which it carries. In order that the spindle maynot rotate except when actuated by the tappets and through itstappet-wheel, a verticallymovable holder 35, having a projection 36,which engages the notches between the teeth of the tappet-wheel, isprovided. Said holder is normally held downwardly by a flat spring 37,which is secured upon a bracket 38, projecting from the support 35 andproviding guiding means for the upper end of the holder which penetratesit. The holder has avertical slot, through which the inner end of thespindle projects, and it furthermore has a roller at its free end, whichbears upon the circular plate and the cams arranged thereon, so as toactuate said holder. The cams are so arranged relatively to the tappetsthat the tappet-wheel is released thereby for rotation just before it isengaged by a tappet and is reengaged by said holder just after saidtappet has effected its actuation.

It should be remarked that preferably three grades of abrading devicesare provided for operating upon the tumblers to produce the facesthereon in completed shape, said abrading devices being disposed ingraduated relation in the machine, so that the tumblers are It shouldalso be remarked that the set of tumblers which is being operated uponis moved bodily, so as to bring the tumblers successively to the variousgrinding devices, which are arranged in the machine stationarily withreference to said tumblers. In view of these facts it will be seen thatthe arrangement of the gearing which drives the disk 8 and the circularplate 11 must be such that the latter will efiect a complete individualrotation of each tumbler before the former effects the movement of theset of tumblers bodily, so as to bring the same to a new position.

The abrading devices may be described as follows: Upon standards39,which are mounted upon and secured to the top plate 2, are arrangednear the tops thereof lugs or projections 41, varying in number from oneto three, as necessity requires. Between the standards 39 are pairsofguide-plates 42 and having upon their adjoining faces guides 43, eachplate being supported upon a standard by means of a bolt 44, whichprojects through a lug upon the outer face of said guide-plate and a lugon the standard. The guides 43 have in their adjoining faces 1dovetailed grooves 45 for the reception of the correspondingly-shapededges of a plate 46, adapted to reciprocate on said guides horizontallywhen actuated bya hooked lever or pawl 46, that is fulcrumed upon an arm47, secured to one of the lugs 41 of the standards, said lever having aslot 49 at its inner end, which receives a pin 50 upon the upper face ofthe plate 46. The lever is adapted to be actuated so as to throw itshooked end outwardly by means of a toothed cam 51, journaled above thestandard 39 and being operated by ashaft 52, to which it is secured atthe upper end thereof, said shaft carrying at its lower end a pinion 53,that is one of a train of similar pinions having similar functions,motion being imparted to said train of pinions from the first one whichengages the pinion 23 through intermediate smaller pinions 54. It shouldbe remarked that each toothed cam 51 is provided with eight teeth, themembers of correspondingly disposed pairs of which are separated by aspace, as shown in Fig. 1.

55 designates one of the abrading-disks, said abrading-disks beingjournaled in the free ends of a bifurcated lever 56, which is fulcrumedat its shank end in a pair of projections 57, extending downwardly fromthe plate 46. The bearing-spindle 58 of the abrading-disk carries a beltwheel or pulley 59,0ver which passes, as shown in Fig. 2, a belt from asuitable driving apparatus that is arranged above the machine, said beltextending in a lar. It will be seen that while being rotated about itsspindle as an axis and while the ma-,

chine is in normal operation the abradingdisk will be given areciprocating motion, which is imparted to it from the toothed cam 51through the lever 46 and the plate in which the bifu rcated lever, whichcarries said abrading-disk, is fulcrumed. By virtue of the motion thusimparted to the abrading-disk the latter is made to act upon the side ofthe tumbler from top to bottom thereof. In order that the action of thedisk upon the tumbler may be uniform at all points upon the latter, pins60 are secured near the free ends of the bifurcated lever 56, projectingoutwardly therefrom and being guided in slots 61, that are formed inplates 62, which plates are secured to opposing faces of the pairs ofguide-plates. It should be stated in order that the abrad ing-disk maybe readily removed from and adjusted in its bearings blocks 63 areprovided in the free ends of said bifurcated lever, said blocksreceiving the ends of the spindle 58 and being adjustably mounted in thelever by means of set-screws 64.

The operation of the machine which has been above described is asfollows: It being assumed that the gearing is properly arranged and thatthe various members thereof are of proper dimensions, the motion whichis imparted from the drive-shaft 16 to the wormwheel 21 and from thenceto the cam 22 and the pinion 23 will effect intermittently the rotationof the notched and scalloped disk and continuously of the gear 15, theresult being a consequent intermittent rotation of the disk 8 and thecircular cam and tappetcarrying plate 11. As hereinbefore set forth, themovements of the disk 8 and the circular plate 11 will effect anintermittent rotation of each tumbler and also an intermittent rotationabout the shaft 10 of the set of tumblers. During each of the rotationsof the tumblers individually in their holders the particular abrading-disk which is acting upon said tumbler is being intermittentlyreciprocated, so as to act upon each face of said tumbler as it ispresented to it. Then the rotation of each tumbler has been completedand when, also, the rotation of the toothed cam '51 has actuated thehooked lever 46 a number of times which corresponds to the numher offaces (or intermittent motions) of thetumbler, said tumbler will then becarried upon the disk 8 to the next position, and during this intervalthe lever 46 will remain inactive, this result being produced by sodisposing the space that is provided between two of the teeth of thetoothed cam that it will be reached by the hooked portion of the leverat a time which coincides with that when the set of tumblers is beingmoved to the new position.

The belt which drives each abrading-disk is arranged at an incline tothe perpendicular, so that it may act upon said disk to return the sameto the position from which it has been moved bythe action of the lever46.

It should be remarked that any suitable and well-known means may beprovided for so acting upon the driving-belt of each abrading-disk as toautomatically efiect a raising of said disk during the intermittentmotions of the tumblers upon which it is acting.

I have found it preferable to use three abrading-disks to produce atumbler having the properly formed and finished faces upon its sides,the first one of said abrading-disks to which the tumblers are eachsubjected being composed of cast-iron, with which sand and water areused, the second one being composed of sandstone, and third one beingcomposed of felt, cork, or similar material. The machine may be builtWith these abradingdisks arranged in two sets, the mechanisms for actingintermittently upon the individual tumblers, as well as the mechanismsfor rotating the sets of tumblers into operative contiguityto thesuccessive abrading devices, bein g correspondingly arranged. For thesereasons the arrangement which is shown in Fig. 1 is provided, whereinappear six complete mechanisms arranged in two sets and wherein a spaceis left at each side of the machine between said sets, said spaces beingleft so that the tumblers may be mounted and dismounted from theirholders without inconvenience.

Having thus fully described myinvention,
